SAR is worth reading up on - very clever use of technology and math.
I am concerned that ESA will be in conflict with the political leadership when it turns out that biomass is increasing with the current climate cycle.
We have 20% more biomass now than forty years ago. Nobody is talking about this, yet if 20% of all biomass had disappeared it would be a five-alarm fire in the press.
It's especially heartening that the deserts are shrinking. This is tremendously valuable to the poorest countries and it's because edge-dwelling plants can keep their stoma a bit more closed, making them more drought resistant while engaging in the same amount of respiration.
More data is always welcome - hopefully it gets published.
